Global Warming: Is it the Unwitting Demise of the Human Race SCI 207 February 25‚ 2013 Global Warming: Is it the Unwitting Demise of the Human Race Since the inception of planet earth‚ the sun has heated the planet. As earth cooled and an atmosphere developed‚ it provided a protective shell that allowed microscopic creatures and plant life to grow. As the species on earth diversified‚ plants began to absorb carbon dioxide and provided oxygen that was needed for animal life. In turn animals

In this lab we tested the purity of water by looking for the chemicals free chlorine‚ chloride‚ sulfate‚ nitrate‚ copper‚ total hardness‚ iron‚ hydrogen sulfide‚ lead‚ pesticides‚ pH‚ total alkalinity‚ and total chlorine inside a water sample. The chemicals that produced a 0.0 result meant that there was no trace of that chemical inside the sample. The chemicals not found were copper‚ hydrogen sulfide‚ free chlorine‚ lead‚ iron‚ pesticide‚ and total chlorine. As a class we found the results of

Is genetic engineering the answer to ending global hunger? SCI 207 March 23‚ 2013 Hunger is one of the root causes to poverty due to the exponential growth of the human population. The effects of hunger are diverse and have a negative effect on the growth and life span of a person. Scientists believe that they can help alleviate hunger problems through alteration and modification of genes in foods. The research in this paper will give the pros and cons of GM foods and help answer the following

Bohnenberger Professor Van Doorn ENVS 150-002 2 March 2015 Water Quality Lab Report Introduction: When people are asked about how water is characterized‚ they usually will think of saltwater‚ freshwater‚ safe-to-drink freshwater‚ and tap water. Only a few people understand that water and its quality are characterized in several other ways beyond salt‚ fresh‚ and tap water. In 1967‚ the Water Quality Act‚ which was an amendment of the Federal Water Pollution Control Act‚ was passed. The Act required

Introduction: This lab investigates the question‚ what is the water quality of the U-High creek based on micro invertebrates found in the creek? There are many factors that affect the quality of water such as phosphorus and nitrogen levels‚ dissolved oxygen‚ and pH. Phosphorus and nitrogen in water can increase the growth of aquatic plants and algae‚ leading to the decomposition of dead plant material and the removal of dissolved oxygen from water. The total nitrogen concentrations for freshwater

Water Quality and Contamination Tamekia Roberts SCI 207: Dependence of man on the Environment Instructor: Michelle Kozlowski November 24‚ 2014 Introduction Background- The ever-increasing popularity of bottled water means that it is important to analyze not only its mineral content but also‚ above all‚ it’s content of possible contaminants‚ especially the organic ones. In this respect‚ bottled waters are a special case‚ because apart from organic chemical contaminants

There are two visible features of contaminated water; colour and smell. Contaminated water usually has unusual smell and coloured. Invisible factors affecting water quality are sources of water. For instance; tap water
